UNCOUPLING DEVICE.

Specification of Letters Patent.

Patented Feb. 3, 1914.

To all whom it may concern I Be it known that we, CHARLES A. CARS- GADIN and GEORGE A. VVOODMAN, citizens of the United States, both residing at Chicago, in the county of Cook and State of Illinois, have jointly invented certain new and useful Improvements in Uncoupling Devices, of which the followingis a specification.

Our invention relates in general to uncoupling devices such as are in use upon railway cars and the like, and aims to provide a new and improved means for removing the locking pin of a coupler of any of the ordinary types.

One of the principa-l objects of our invention is to provide a car uncoupling device which may be operated from the side of the car and which willbe made of two sections of metallic tubing telescoping one within the other, one of these sections being secured to the car body and the other to the locking pin of the coupler, obviating thereby the use of chains, links and clevises at present employed to connect a device of this character to the locking pin.

A further object of the invention. is to so construct and arrange the parts of the uncoupling device that should the draft bar or other members he pulled from the car body the uncoupling device will not be torn away.

Further objects and advantages of our invention will be apparent as it is better understood from the following description which, taken in connection with the accompanying drawing, illustrates one preferred embodiment thereof.

On the drawing :-Figure 1 is a top plan view of a portion of a car and coupler provided with an uncoupling device made in pursuance of our invention; Fig. 2 is afront elevation of the device as shown in Fig. 1 with parts broken away, and Fig. 3 is an end elevation looking toward the right of Fig. 2.

For the purpose of illustrating our invention we have shown a coupler 10 of any of the usual types secured to the end 12'of a freight car and having a single locking pin 11. coupler casting 13, the knuckle 1 1, the lmuckle-pin 15 and the locking pin 11.

The uncoupling device is formed of two sections 16 and 17. The section 16 is preferably composed of a single hollow tubular The coupler shown comprises themember having its ends 18 and 19 bent at,

plurality of brackets 20 fastened to the car body so that the main portion of the memher is disposed substantially in a horizontal plane. The section 17 is composed of a tube or solid rod of smaller diameter than the section 16, and has its ends 21 and 22 bent substantially at right angles to each other and connected together by an inclined portion 23, said portion being disposed substantially at right angles to the end 21'and inclined, as will be hereinafter disclosed, to the end 22. The diameter of this section is of proper dimension to permit it tofit and move freely within the aperture 24 of the locking pin 11. The arm 21 of the section 17 is, when the parts are assembled and posit-ioned upon a car, disposedwithin and slidably movable with relation to the end 18 of the section 16 which is located in the same vertical plane with the axis of the looking pin 11 when the latter is in central position. The other end 22 of the section 17 is positioned loosely within the eye of the locking pin. This end is of sufficient length to permit the locking pin to slide freely thereon as the cars travel around a curve, being given the necessary length by inclining the portion 23 as is shown in Fig. 2 and extending the end 22 beyond the lockingpin a distance substantially equal to the distance between the locking pin and the connection between the end 22 and the portion 23 when the coupler is in central position.

When itis desired to uncouple a car provided with an uncoupling device made in pursuance of our invention the handle 19 may be raised, thereby elevating the end 18 and lifting the locking pin 11 by means of the member 17. The sliding connection be tween the section 17 and the section 16 will permit this pin to be raised substantially It is obvious that various changes may be made in the form and construction of the parts and their arrangements without departing from the spirit and scope of our invention, or sacrificinv any of its benefits, the form hereinbefore described being merely one preferred embodiment thereof.

We claim 1. A car uncoupling device comprising a pair of rigid sections, one adapted to be secured to a car and the other to the locking pin of the coupler, the former section having an arm disposed above the locking pin and the latter section comprising a portion extending upwardly from the locking pin to a point in line with said arm, and a portion extending from the upper end of said upwardly extending portion into telescopic connection with said arm of the former section.

2. A car uncoupling device comprising two sections telescoping together at their adjacent ends, one of said sections being adapted to be secured across the end of the 1 car and having an arm extending outwardly from the pivotal axis of the said section, the other section having its ends bent at right angles to each other and connected by a portion inclined to one of said ends and at right angles to the other, one of said ends being adapted to telescope with the outwardly extending arm of the first-named section and the other end to be inserted within the eye of the locking pin of the coupler to slidably connect the said pin to the said section.

3. A car uncoupling device comprising two sections, one of said sections being adapted to be plvotally secured, across a car and having an arm extending outwardly and the other end being adapted to detachably telescope with the outwardly disposed arm of the former section whereby the sections will be disconnected should the coupler be torn from the car.

4. A car uncoupling device comprising two sections telescoping together at their adjacent ends, one of said sections being adapted to be secured across the end of a car and having an arm extending outwardly from the pivotal axis of the said section and the other section, comprising a body portion and an arm angularly disposed with respect to the said body portion at each end of the body portion, one of said arms being adapted to telescope with the outwardly extending arm of the first named section and the other to be slidably inserted within the locking pin of the coupler.
